Advantage:
Wear resistance, high impact, high drilling rate,high core recovery,long life
Which impregnated diamond oil drilling bit eight overall use of spiral arc oblique blades moder ate design,
sintered by the self-sharpening blade type impregnated with tungsten carbide blocks from the matrix body.
The catalytical techniques used in hydraulic fluid power design,using a strong high -pressure water jet
and rotary joint breaking rocks and clear debris,oblique arc spiral maximized flute better cleaning and cooling
the drill bit.Heavy large particles of single crystal diamond and alloy powder formed by high-temperature
pressure impregnated blocks through continuous self-sharpening cutting unit exposed sharp,
drill in extremely hard, highly abrasive formations have higher ROP and longer life.
